*	fix fesetenv(FE_DFL_ENV) on x86_64 (see previous commit)	Szabolcs Nagy	2014-02-09	1	-1/+1
*	fix fenv exception functions to mask their argument•••fesetround.c is a wrapper to do the arch independent argument check (on archs where rounding mode is not stored in 2 bits __fesetround still has to check its arguments) on powerpc fe*except functions do not accept the extra invalid flags of its fpscr register the useless FENV_ACCESS pragma was removed from feupdateenv	Szabolcs Nagy	2013-08-18	1	-4/+7
*	optimize x86 feclearexcept: only use save/restore x87 fenv if needed•••the x87 exception summary (ES) and stack fault (SF) flags may be spuriously cleared by feclearexcept using the fnclex instruction, but these flags are not observable through libc hence maintaining their state is not critical.	Szabolcs Nagy	2013-08-18	1	-15/+11
*	add sse fenv support on i386 through hwcap•••the sse and x87 rounding modes should be always the same, the visible exception flags are the bitwise or of the two fenv states (so it's enough to query the rounding mode or raise exceptions on one fenv)	Szabolcs Nagy	2013-08-18	1	-3/+0
*	try fixing/optimizing x86_64 fenv exception code•••untested; may need followup-fixes.	Rich Felker	2012-03-17	1	-18/+23
*	fix x86_64 fe[gs]etround, analogous to nsz's x86 changes	Rich Felker	2012-03-17	1	-8/+9
*	use type directives for fenv asm functions	Rich Felker	2011-06-28	1	-0/+7
*	x86_64 fenv support (untested; at least known to build successfully)	Rich Felker	2011-06-13	1	-0/+88
